2. Fight against pollution.

3 adhere to the principle of overall greening and national greening, and carry out greening activities. According to the idea of "stopping new species and gradually withdrawing", we will focus on eucalyptus substitution in major ecologically sensitive areas to create a good forest landscape and improve the level of ecological functions. We will carry out a three-year campaign to improve the rural living environment, promote the "toilet revolution" in an orderly manner, improve the rural garbage, sewage and village appearance, implement the comprehensive management project of natural villages and the renovation project of hollow villages, and build "beautiful and livable" villages. Strengthen the "three lines and one order" constraint. Strengthen the management of space, total amount and access environment with red line of ecological protection, bottom line of environmental quality, online utilization of resources and negative list of environmental access. Strengthen forest protection and carry out in-depth ecological protection and restoration projects of rural landscape forests, fields, lakes and grasses. With the goal of building an ecological pastoral scenery with "forests by the village, gardens in the village, tree-lined roads and flowers", we will implement rural greening and beautification projects, and do a good job in afforestation, village greening and courtyard beautification around hills and towns.

Red line of ecological protection: refers to the area in the ecological space that has special and important ecological functions and must be strictly protected. It is the bottom line and lifeline for safeguarding and maintaining national ecological security, and usually includes important areas with ecological functions such as important water conservation, biodiversity protection, soil and water conservation, windbreak and sand fixation, coastal ecological stability, and sensitive and fragile areas with ecological environment such as soil erosion, land desertification, rocky desertification and salinization. Strict control shall be implemented according to the basic requirements of "no reduction in ecological function, no reduction in area and no change in nature". The bottom line of environmental quality: refers to the requirements of regional and phased environmental quality objectives, corresponding environmental management and control, pollutant emission control, etc. determined according to the principle of continuous optimization of water, atmosphere and soil environmental quality, combined with the requirements of environmental quality status, relevant planning and functional zoning, and considering the improvement potential of environmental quality. Online utilization of resources: it refers to the online control requirements for the total amount, intensity and efficiency of resource development and utilization in different regions and stages by using the balance sheet of natural resources and combining with the control of natural resources development with the principle that natural resources assets can only increase in value but not depreciate, with the purpose of ensuring ecological security and improving environmental quality.
